## List Files

- `limit: optional number`

  Number of items to return per page.

  Defaults to `20`. Ranges from `1` to `1000`.

- `page: optional string`

  Opaque page cursor returned in a prior list response's `next_page`. Prefixed `page_`.

  - `downloadable: optional boolean`

    Whether the file can be downloaded.

  - `expires_at: optional string or null`

  Opaque cursor for the next page. Supply as `?page=` to fetch the next page; null when there are no more results.
